The Czech firm Mjölk architects, headed by Jan Mach and Jan Vondrák, has refurbished an abandoned cottage in the Horská Kamenice river valley, in Jiřetín pod Bukovou, a municipality in the Liberec Region.

In a beech forest, surrounded by mountains, two volumes are externally clad in vertical blackened timber panels that form a continuous surface rising from the ground and all the way to the tops of the pitched roofs. The 85.5-square-meter main house has been reorganized to maximize the simple, functional interior space. A staircase hidden inside a closet leads to the larger of two bedrooms. The smaller, 21-square-meter construction contains a sauna and a guestroom.
